SUPPORT FOR SPINNING-SPINDLES. v

SPECIFICATION forming part of Letters Patent No. 408,165, dated July 30, 1889.

Application filed June 5, 1889. Serial No. 313,179. (No model.)

To aZZ whom it may concern.-

Be it known that I, GEORGE OTIS DRAPER, of Hopedale, county of lVorcester, State of Massachusetts, have invented an Improvement in Supports for Spinning-Spindles, of which the following description, in connection with the accompanying drawing, is a specification, likeletters on the drawing representing like parts.

This invention has for its object to improve the construction of spindle-bearings In accordance with my invention I have combined with a sleeve-whirl spindle and a supporting case or holder astep-block mounted loosely therein and bored at its upper end and extended up into the supportingcase within the whirl, and within the hollow upper end of the step-block I have placed loosely a bolstentube, thus compounding the bearing a in the line of the band-pull, the bearings for the spindle, as herein shown, being restrained from rotation in the supporting-ease by a pin or projection.

The drawing in partial elevation and section represents a spindle and bearings embodying my invention.

The rail D receives and has secured to it in usual manner the supporting case or holder E, and they and the spindle F and its attached sleeve-whirl G are and may be all as usual.

Inside the supporting-case I have placed loosely a step-block 0, consisting of a portion bored to receive the small end 2 of the spindle, and above the bore, which is entered by the said small end of the spindle and rigid with the step-block, is a tubular portion a. The internal diameter of the tubular portion a" of the step-block a is of suflicient size to receive loosely a bolstcrtube 1), thus comthus obtaining a double cushion for the Spindle in its wanderings.

I have shown the bolster-tube and the stepblock as restrained from rotation with the spindle by the same pin or projection 3.

I elaim- The combination, with a sleeve-whirl spindle, a step-block a to constitute a lateral bearing for the lower end of the spindle and having a tubular extension to rigidly connected thereto, and a supporting-case in which the said step-block is mounted loosely, of a bolster-tube placed loosely in the tubular portion of the step-block, substantially as de scribed.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEO. OTIS DRAPER.
